Everything is good but when you save a screenshot it saves it with the same name everytime so you have to rename the file after every screenshot otherwise it replaces it. It's not a big issue but it would be nice if it saves every screenshot as a new file.
I'll consider it for the next version (if there will ever be one).
I'm curious though, I can ss 200 bpm streams in osu but I can't even get 190 bpm for more than a second in this program. Are streams in osu slower than the bpm says they are?
I'm pretty sure it's accurate. Maybe it's the missing music or circles that affect you.
